ATTACHIKENT ARl IFICIAL LIIVIBS.

Application filed November 8, 1920.

To all whom it may concern:

Be it known that I, HARRY Groom), a citizen of the United States,residing at Kingston, in the county of Luzerne and State ofPennsylvania, have invented new and useful Improvements in Attachmentsfor Artificial Limbs, of which the following is a specification.

This invention relates to improvements in artificial legs, the principalobject of the invention being to provide improved means for connectingthe chord which connects the foot part with the shank, to the said footpart and shank. I

Another object oi the invention is to provide a bearing platetorconnection with the foot part to which the chord and the ankle boltare connected.

T his invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which l igure lis a view partly in section showing my improved artificial leg.

Fig. 2 is a bottom plan view of the foot part of the leg.

lsig. 3 is a perspective view of the plate.

Fig. l is a view of a modified form of the plate.

Fig. is a sectional view on line 5-5 of Fig. 1.

In these views 1 indicates the foot part of the leg and 2 the shankpart. These parts are connected together by the flexible chord 3, theelastic strap 3' and the ankle bolt 4 which is provided with the pivotaljoint 5. These parts are constructed as usual and will. not be describedin detail. T he upper ends of the chord 3 and strap 3 are held to part 2by means of a wooden pin 6 which passes through eyes in the upper endsof said parts and has its ends seated in bushings 7 located in holes inthe walls of part 2.

The under face 03": the heel part of foot 1 is recessed to receive plate8 which is provided with the opening 9 and the strip on each side ofsaid opening being bent upwardly to form the loop 10. The lower end ofchord 3 fits between these loops and the specification of LettersPatent.

beam or pin 11, formed of hard wood, is passed through the eye in thisend oi the chord 3 and has its ends engaging the loops. The plate isprovided with an extension 12 which is connected with the main part ofthe plate by the right angular portion 14:. This part 12 is providedwith a hole 15 to receive the threaded end of the anlde bolt 41: andacts as a washer for th nut 16 on said bolt. The rear end of the plateis provided with an upwardly extending tongue 17 which engages the heelof the foot part and acts to stabilize the parts.

011 the old style of legs the parts 12 and 14 can be omitted from theplate, as shown in Fig. l, as in this case the washer is not needed.

From the above it will be seen that chord 3 can easily be removed andreplaced by a new one by knocking out the pins 6 and 11. The plate whichforms the bearing for pin 11 will prevent the crushing of the wood, fromwhich the foot part l'is formed, by said pin as is the case in woodenlegs now on the market.

Nhere a metal foot is used the plate is not.

necessary and the pin 11 only is used.

It is thought from the foregoing descrip tion that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims.

lVhat I claim is 1. An artificial leg comprising a foot and a leg partpivotally connected together, a plate in the heel portion of the footpart, a pin, means for removably holding the pin on the plate and achord connected with the leg part and having its lower end engaged bythe pin.

2. An artificial leg comprising a leg part and a foot part pivotallyconnected together, a plate in the heel portion having a slot therein,loops on the plate, one on each side of the slot, a chord connected withthe leg part and having its end located between the'loops and a pinengagingthe loops and passing through the eye in said chord.

3. An artificial leg comprising a leg part and a foot part pivo a platein the heel portion having a slot therein, loops on the plate, one oneach side of the slot, a chord connected with the leg part and havingits lower end located between the tally connected together,"

loops, pin en aging the loops and passing extending loops thereon spacedapart, said through the eye in said chord and an up chord. havi; aperforated lower end located wardly extending tongue on the rear partbetween the loops a pin engaging said. loops of said plate engaging therear of the heel and passing; through the perforation and an 5 part ofthe foot. extension on the plate having an opening 15 lin combinationWith the leg ancl'ioot therein for receiving the end of the ankle partsof an artificial leg, a chord connecting bolt and a Washer therefor.

said parts together, an ankle bolt also con In testimony whereof I affixmy signature. nectmg the parts together, a plate in the 10 lower face ofthe "foot part having upwardly HARE Y GOULD.
